The document describes the user interface of the EMA3100A Target Motion Simulator. It includes menus, toolbars, and forms that allow users to create and manage motion modeling and target tracking projects. Key features of the user interface include creating and opening projects, modeling paths and trajectories, defining sensor models, and viewing simulation results. Tools are provided for path modeling, combination, and trajectory viewing. The interface provides a consistent set of elements for configuring, running, and analyzing simulations.
